Definitions
- the present invention relates to a hot plate and a conductive paste using a ceramic substrate.
- a heating device called a hot plate In the semiconductor manufacturing process, for example, when heating and drying a silicon wafer that has undergone a photosensitive resin coating step, a heating device called a hot plate is usually used.
- a ceramic substrate such as alumina has been often used as a hot plate forming material.
- a resistor as a conductor layer is formed in a predetermined pattern on one side of the alumina substrate, and a terminal connection pad is formed on a part of the resistor.
- Such a conductor layer is formed by printing and applying a silver paste for an alumina substrate to the substrate, and then heating and baking. After that, terminal pins are soldered to the pads, and power is connected to the terminal pins via wiring. Then, a silicon wafer to be heated is placed on the upper surface side of the hot plate, and a current is applied to the resistor in this state, so that the silicon wafer is heated to 10 ° C or more. .
- the conductive paste for forming the conductive pattern layer is silver particles of 60% by weight to 80% by weight. /. And glass frit based on lead silicate 1 weight 0 /. One containing 10 to 10% by weight, a binder of 1% to 10% by weight, and a solvent of 10% to 30% by weight is commonly used. No. 9). In particular, glass frit, which is a sub-component, is required to ensure favorable adhesion to the conductor pattern layer.
- the above-mentioned conventional lead-based paste is directly used as an aluminum nitride substrate or carbonized
- a ceramic substrate such as a silicon substrate
- the heat generated during the paste baking causes oxides in the paste to act on the aluminum nitride, causing a reaction that generates a large amount of alumina and nitrogen gas.
- the main reason for this is thought to be the high content of oxides, especially lead oxide, in the glass frit.
- the high-pressure nitrogen gas generated at the time of the first baking passes through the grain boundaries of the silver particles and tends to be forced out. As a result, blisters are likely to occur in the conductor pattern layer, and the precision of pattern formation deteriorates.
- the specific resistance of the conductor pattern layer may be desirable to increase the specific resistance of the conductor pattern layer compared to the current one.
- the ratio of the conductive component occupying the conductive pattern layer is reduced, and as a result, the specific resistance is reduced. Increase.
- An object of the present invention is to provide a hot plate provided with a conductive pattern layer having little swelling, excellent adhesion, and high specific resistance, and a conductive paste suitable for the production thereof.
- a hot plate using a ceramic substrate provided with a conductor layer.
- the conductor layer is composed of ruthenium oxide, glass frit, and noble metal particles.
- the conductor layer contains ruthenium oxide. For this reason, even if the amount of glass frit added is set to be large (10% by weight or more based on the noble metal) in order to increase the specific resistance, the reaction between the glass frit and the ceramic substrate is suppressed. It can suppress the occurrence of blistering of the conductor layer. Therefore, a conductor layer having little swelling and a large specific resistance of 10/0 * 0; 1 11 or more can be obtained.
- ruthenium oxide itself is a machine that increases the specific resistance. It is considered to have the ability.
- the conductor layer is preferably made of ruthenium oxide, bismuth or its oxide, glass frit, and noble metal particles. By adding bismuth or its oxide, the reaction between the glass frit and the ceramic substrate is further suppressed, so that a conductor layer having excellent adhesion can be obtained.
- the ceramic substrate is preferably a nitride ceramic substrate or a carbide ceramic substrate.
- a nitride ceramic substrate or a carbide ceramic substrate thermal conductivity and high-temperature heat resistance are improved.
- an aluminum nitride substrate having excellent heat resistance and high thermal conductivity a practical hot plate that can withstand use at high temperatures can be obtained.
- the glass frit preferably contains zinc borosilicate.
- the glass frit containing zinc borosilicate differs from the conventional product containing lead borosilicate in that the amount of oxide that reacts with the nitride on the ceramic substrate to generate nitrogen gas is small. Therefore, even if the conductor layer is formed using a material containing zinc borosilicate as a component, a large amount of nitrogen gas is not generated, and the conductor layer is less likely to blister.
- the noble metal particles are preferably at least one selected from gold particles, silver particles, platinum particles and palladium particles. Since metal particles that are relatively resistant to oxidation even when exposed to high temperatures and have a sufficiently large resistance value are used, a conductor layer suitable as an antibody for generating heat can be easily obtained.

- the base end of the terminal pin 12 made of a conductive material is soldered to each pad 10a. As a result, electrical continuity between each terminal pin 12 and the wiring resistor 10 is achieved.
- a socket 6 a at the end of the lead wire 6 is fitted to the end of each terminal pin 12. Therefore, when a current is supplied to the wiring resistance 10 via the lead wire 6 and the terminal pin 12, the temperature of the wiring resistance 10 rises, and the entire hot plate 3 is heated.
- a mixture is prepared by adding a sintering aid such as yttria or a binder to the ceramic powder, if necessary, and the mixture is uniformly kneaded using, for example, a three-roll mill. Using this kneaded material as a material, a plate-shaped formed body having a thickness of about 1 to 100 mm is produced by press molding.

- the specific resistance decreases due to an increase in the ratio of the conductive component in the wiring resistance 10.
- the amount of the noble metal particles is too small, it is preferable from the viewpoint of an increase in the specific resistance, but on the other hand, the amount of the glass frit is relatively large, and blistering is likely to occur.
- the amount of glass frit is too large, blistering is likely to occur in the wiring resistance 10.

Conversely, if the content of bismuth or bismuth oxide is too large, the noble metal and bismuth or bismuth oxide do not mix, and the resistance value varies. Further, the noble metal paste P1 needs to contain ruthenium oxide (RuOJ. In this case, ruthenium oxide is made of bismuth or bismuth oxide together with glass frit and ceramic substrate such as aluminum nitride. It is thought that by appropriately suppressing the reaction with, generation of reactive gas is prevented.
